But the important thing to realize is that "not found" status is different from "failed" status (e.g. non-existing DNS record vs failing DNS server), and that mdns_minimal always fails if this is not a zeroconf hostname (name ending with .local etc.). So by now I understand why [NOTFOUND=return] is where it is and it looks reasonably. There are two problems here: * mdns_minimal times out; it seems that it does that while talking to avahi, can you also attach strace to avahi daemon and have a look at what is it doing? * mdns_minimal returns not-found instead of failure on timeout. Looks like simply a bug. Then there is a third problem that it seems nss_mdns is currently unmaintained; if we can't solve this bug, I think we will have to discuss in the opensuse community whether to continue shipping nss_mdns. But let's see if something won't be obvious from avahi strace first. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

[NOTFOUND=return] before "dns" entry causes, that dns will be never used if mDNS fails .. default behaviour is [NOTFOUND=continue] .. i am wondering why you've closed a bug .. even if mDNS works good, but not for *.local namespace, default ^hosts: entry is in SUSE bad !! it doesn't give any sense imho to have it this order .. regards -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
